As learnt in @9566

B cl_{3}\rightarrow sp^{2}, trigonal planar

Brcl_{3} \rightarrow sp^{3}d, T-shaped

NH_{3}\rightarrow sp^{3}, pyramidal

NO_{3}^{-} \rightarrow sp^{2}, trigonal planar

NF_{3}\rightarrow sp^{3}, pyramidal 

BF_{4}^{-}\rightarrow sp^{3}, tetrahedral

NH_{4}^{+} \rightarrow sp^{3}, tetrahedral


Option 1)

[BCl3 and BrCl3]

This option is incorrect.

Option 2)

[NH3 and \text{NO}_{3}^{-}]

This option is incorrect.

Option 3)

[NF3 and BF3]

This option is incorrect.

Option 4)
